LOL, really? This stuff will do nothing at all for your intake valves. With direct injection, fuel/air mix is not introduced through the intake valves, only air and crankcase vapors. Direct injection is just that, injector injects fuel directly into the cylinder. With port injection, it might do something, but I won't waste any money on a company that misleads like those guys.

Better yet, what does the owners manual say about fuel additives?

There are 2 bottles one you add to the oil and one to fuel ,and another canister (kinda looks like an ac recharge cannister) you hook up to a vacumn line that sprays directly into the intake manifold a moderate rate, i tried it out yesterday i was being brave lol and having no issues so far , i also installed a upr catch can and new 02 sensor and cleaned map sensors at the same time and i must say my truck is running pretty damn good right now (fingers crossed)

If it worked for ya, cool. I've never used anything that made much of a difference. I know there's many that swear by Sea Foam, I've tried it, and the only thing I saw was a bunch of smoke, really noticed no performance gains.

Maybe just the combination of the things i just cleaned up n what not and i was previously driving with the Check engine light on for a couple weeks but using it makes me feel a lil better, now that i have my catch can on

Chances are you didn't hurt a thing using that stuff, and the theory sounds good. Got to agree with cleaning the other stuff, that's worked for me in the past.

Never put anything in the crankcase but the correct grade of oil the truck calls for and nothing else. I personally won't run anything through the intake of one either, but to each his own.
